Abstract
The utility model discloses a catching device for fishes of different grades and specifications. The catching device comprises a specification dividing box which is a cuboid-shaped frame, wherein parallel inserting bras with uniform interval are arranged in a lower frame and three side frames; a mesh is arranged on the last side frame; an opening is formed in the mesh; a funnel-shaped inlet facing to the interior of the box is arranged on the opening. The catching device cannot harm the fishes, and the fishes of different sizes and specifications can be separated anytime.
Description
Technical field
The utility model belongs to fish culture technical field, is specially the device of fishing for that relates to a kind of different brackets specification fish.
Background technology
In Fishery breeding process, in certain sealing water body environment, carry out fat thick, the seedling fostering stage is all that density is large, the inhomogeneous unification of specification often needs screening.Traditional method is to surround and seize and carry out selective filtering screening in whole pond.Such mode of operation, all will operate whole fingerlings, must make the innocent suffer.Affect the growth of other individuality, even have damage in various degree.Particularly choosing quantity when few, consuming time especially, consumption power, work consuming.The formula of releasing operation at oceanic pasture more highlights, and species individuality is little, and the natural predatoriness that the weak are the prey of the strong injures, and is unfavorable for the rapid propagation of population quantity.Can only constantly screen continually and conform with the specification kind of putting in a suitable place to breed, therefore at the thick fingerling pond of fat, a kind of special instrument is particularly important.
Utility model content
The purpose of this utility model is to provide the device of fishing for of a kind of different brackets specification fish, and this device can not injure fish body, isolates at any time the fisheries biology of different size size.
Above-mentioned purpose of the present utility model is achieved by the following technical solution: a kind of different brackets specification fish fish for device, it is characterized in that comprising a minute specification casing, described minute specification casing is cuboid framework, wherein in underframe and three body side frames, be provided with the uniform inserted link in the interval paralleling, on a body side frame of residue, be provided with net sheet, on described net sheet, be provided with opening, on described opening, be provided with the falred entrance towards box house.
As a kind of improvement of the present utility model: be also respectively arranged with barrier net on the two vertical opposite side of body side frame that are provided with net sheet, one end of described barrier net is fixed on two vertical opposite side of described body side frame, the other end is fixed on spud pile, and described spud pile is fixed on pond bottom.
As further improvement of the utility model: the utility model is provided with aerator near the described body side frame opposite side framework that is provided with net sheet.
The framework of described cuboid framework is provided with jack, and the two ends of described inserted link are fixed on cuboid framework by described jack.
As of the present utility model, further improve: on the upper frame of described cuboid framework, be also provided with part inserted link.
The utility model is provided with the opening of being convenient to fish for required specification fish on upper frame.
The utility model has the advantages that: the different brackets specification fish that provide in the utility model fish for device, easy to make, cost is low, simplified traditional mode of operation, do not injuring under the prerequisite of organism, efficiently the biology of separation screening different size, is applicable to the large cultivation of producing, the specification of the object of releasing of artificial releasing's aquaculture of oceanic pasture is cultivated with screening all very important, can play guaranteeing role to improving production efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of fishing for minute specification casing in device of the different brackets specification fish that adopt in embodiment;
Fig. 2 is the scheme of installation of fishing for net sheet in device of the different brackets specification fish that adopt in embodiment;
Fig. 3 be in embodiment different brackets specification fish fish for device fish for screening schematic diagram.
Embodiment
The different brackets specification fish that the present embodiment provides fish for device, as shown in Fig. 1-3, comprise a minute specification casing, this minute specification casing is cuboid framework 1, wherein in underframe and three body side frames, be provided with the uniform inserted link 2 in the interval paralleling, on a body side frame of residue, be provided with net sheet 3, on net sheet 3, be provided with opening 4, on opening 4, be provided with the falred entrance 5 towards box house, this falred entrance 5 can adopt the materials such as bamboo chip to make.
On the two vertical opposite side of body side frame that are provided with net sheet, a barrier net 6 is also set respectively, one end of barrier net 6 is fixed on two vertical opposite side of body side frame, and the other end is fixed on spud pile 7, and spud pile 7 is fixed on pond bottom.Between body side frame, two barrier nets, form the trip of water conservancy diversion fish to water conservancy diversion region, fish can enter in minute specification casing along water conservancy diversion region.
Be provided with net sheet body side frame opposite side framework near be provided with aerator 8.
While fishing for, open aerator 8, aerator 8 drives current to form circulation, because fish have the contrary habit that becomes to flowing, fish swim over to water conservancy diversion region and enter minute specification casing from falred entrance from waters collection around, and in fish, the individuality of not enough specification is slipped away between minute inserted link of specification casing, individuality up to specification is trapped in minute specification casing, pull out, by adjustment, divide the quantity of inserted link in specification casing, can isolate at any time the fish of required different size size.
The framework 9 of cuboid framework is provided with jack 10, and the two ends of inserted link 2 are fixed on cuboid framework 1 by jack 10.
On the upper frame of cuboid framework 1, be also provided with part inserted link, on upper frame, be provided with the opening 11 of being convenient to fish for required specification fish simultaneously.
More than enumerating specific embodiment describes the utility model.It is to be noted; above embodiment is only for the utility model is described in further detail; do not represent protection domain of the present utility model, nonessential modification and adjustment that other people make according to prompting of the present utility model, still belong to protection domain of the present utility model.
